Power Conversion System

Safety requirements for power semiconductor converter systems - Part 2: Power Electronic Converters from 1000 V a.c. or 1500 V d.c. up to 35 kV a.c.

This International Standard deals with the safety of electric battery chargers for household and similar use having an output at safety extra-low voltage, their rated voltage being not more than 250 V.
Battery chargers not intended for normal household use, but which nevertheless may be a source of danger to the public, such as battery chargers intended for use in garages, shops, light industry and on farms, are within the scope of this standard.

This Standard specifies the test method for measuring and reporting the energy performance of large battery charger systems.

Description: Revision of IEEE Std 946-1992 Guidance for the design of the DC auxiliary power systems for nuclear and non-nuclear power generating stations is provided by this recommended practice. The components of the DC auxiliary power system addressed by this recommended practice include lead-acid storage batteries, static battery chargers, and distribution equipment.

Description: Considered in this guide are the components of both the ac and dc systems and the provided guidelines and recommendations for designing the appropriate systems for the substation under consideration. This guide includes the low-voltage auxiliary systems from the source(s) to the distribution point(s). Reliability requirements and load characteristics are discussed and distribution methods are recommended.

1.1
This Standard applies to ac and dc type power conversion equipment (PCE) that
a) is of dry or liquid-filled construction;
b) has a rated voltage not exceeding 1500 V; and
c) is for commercial, industrial, and residential indoor and outdoor use in nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I.
1.2
Clauses 1 to 6 are general, and apply, unless otherwise noted, to all PCE.

Preface:
This is the third edition of CSA C381.2, Energy performance of battery-charging systems and uninterruptible power supplies. It supersedes the previous editions published in 2014 and 2008 under the title, Test method for determining the energy efficiency of battery-charging systems.
This Standard specifies requirements, definitions, and test methods for determining the energy performance of battery-charging systems.
Scope:

Scope

1.1.1
This Model Code provides marking and test/construction requirements for the field evaluation of electrical equipment by an inspection body, where certification of that equipment is impracticable or otherwise unavailable.

1.1.2
Field-evaluated equipment found to be in conformity with the requirements of this Model Code is considered to be acceptable to the AHJ.

1.1.3

1 Scope
1.1 These requirements cover battery chargers rated 600 volts or less. They are intended to be used in accordance with the National Electrical Code, NFPA 70, to charge industrial storage batteries which are used to provide power for material handling trucks, tractors, personnel carriers, and similar motive equipment. These chargers may be either cord and plug connected or permanently connected.
